(1)We consider the nonemptiness problem for Streett automata: We are given a directed graph G = (V, E) with n = ¦V¦ and m = ¦E¦, and a collection of pairs of subsets of vertices, called Streett pairs,〈L i , U i 〉, i = 1.k. The question is whether G has a cycle (not necessarily simple) which, for each 1 ≤ i ≤ k, if it contains a vertex from L i then it also contains a vertex of U i . Let b=Σ i=1..k |L i |+|U i |. The previously best algorithm takes time O((m + b) min{n, k}). We present an algorithm that takes time 𝑂(𝑚min{𝑚𝑙𝑜𝑔𝑛,‾‾‾‾‾‾√𝑘,𝑛}+𝑏𝑚𝑖𝑛{𝑙𝑜𝑔𝑛,𝑘}). (2)In communication protocol pruning we are given a directed graph G = (V, E) with l special vertices. The problem is to efficiently maintain the strongly-connected components of the special vertices on a restricted set of edge deletions.

IfT is a tree on {1,2, . . , n}, we let T]L denote the subtree of T induced by the nodes of L and all their ancestors. The consensus tree problem asks whether there exists a tree T* such that for every I, T’ IC(Ti) is homeomorphic to Ti. We present algorithms which test if a given set of trees has a consensus tree and if so, construct one. The deterministic algorithm takes time min{O(mn’/‘), O(m + n2 logn)}, where m = Ci IZl and uses linear space. The randomized algorithm takes time O(m log3 n) and uses linear space. The previous best for this problem was an 1981 O(mn) algorithm by Aho et al. Our faster deterministic algorithm uses a new efficient algorithm for the following interesting dynamic graph problem: Given a graph G with n nodes and m edges and a sequence of b batches of one or more edge deletions, then after each batch, either find a new component that has just been created or determine that there is no such component. For this problem, we have a simple algorithm with running time O(n2 log n + be min{ n2, m log n}), where be is the number of batches which do not result in a new component. For our particular application, bc 5 1. If all edges are deleted, then the best previously known deterministic algorithm requires time O(mJ;ii) to solve this problem. computational evolutionary biology. The first application is in the problem of inferring consensus of trees when there can be disagreement[l6]. There have, been several models suggested for this problem[2, 3, 4, 8, ?, 11, 17, 181, of which one is called the Local Consensus Tree[l5]. The local consensus tree model presumes that the user provides a local consensus rule which determines the form of the output tree on (perhaps) each triple of leaves, and the objective is to determine whether a tree exists which is consistent with each of the constraints. We will show that we can construct the local consensus tree of k trees on n species in O(kn3) time, improving on the O(lcn3 + n”) running time if we use the Aho et al algorithm. The second application is a heuristic for constructing the maximum likelihood tree based upon combining solutions to small subproblems. This is a simple and yet potentially significantly interesting approach to the evolutionary tree construction problem. }, author = {Henzinger, Monika H and King, Valerie and Warnow, Tandy}, booktitle = {7th Annual ACM-SIAM Symposium on Discrete Algorithms}, isbn = {0898713668}, location = {Atlanta, GA, United States}, pages = {333 --340}, publisher = {Society for Industrial and Applied Mathematics}, title = {{Constructing a tree from homeomorphic subtrees, with applications to computational evolutionary biology}}, year = {1996}, } @article{2725, abstract = {We prove that the two dimensional free magnetic Schrödinger operator, with a fixed constant magnetic field and Dirichlet boundary conditions on a planar domain with a given area, attains its smallest possible eigenvalue if the domain is a disk.

We follow the growth of isolated spherically symmetric density peaks starting from the linear perturbative regime. The initial parameters correspond to density peaks of various widths and heights in a cold dark matter cosmology. We use a one-dimensional spherical Lagrangian hydrodynamics code to follow the dynamical, thermal, and nonequilibrium chemical evolution of the gas. The system includes a collisionless dark matter component and a baryonic component composed of the nine species H, H^-^, H^+^, He, He^+^, He^++^, H_2_, H_2_^+^, and e^-^. All relevant chemical reactions between these species and their cooling mechanisms are included in the calculations. We explore the dependence of the dynamical evolution of the gas on two parameters: the initial mass scale and the initial overdensity of the system. We follow the evolution of the density, temperature, and abundance profiles within the cloud, assuming two types of central boundary conditions for the collisionless component: in one the infalling dark matter virializes through a reflection from a hard sphere, while in the other it accretes onto a central sink. We find that in both cases, radiative cooling by H_2_ affects the collapse dynamics of the gas only after it has already virialized and become part of the bound object. Therefore, radiative cooling is unlikely to have triggered the initial collapse of perturbations at redshifts z > 10. Nevertheless, baryonic objects with masses well below the linear theory Jeans mass (<~10^3^ M_sun_) form at high redshifts because of shell crossing by the dark matter.
